This projects consists of two parts.

• Main project
• Children project for separate library, to demonstrate usage of Boot and Lein checkouts feature.

Start the app for development

Boot

• All: Install the child project to local Maven repo: cd checkouts/example-component-lib; boot build
• Cursive: boot dev and connect to remote repl
• Fireplace: boot dev and connect to remote repl
• Cider: boot dev and M-x cider-connect

Lein

• All: Install the child project to local Maven repo: cd checkouts/example-component-lib; lein install
• lein less4j auto
• lein figwheel
• Cursive: Start repl from cursive or lein repl and connect to remote repl
• Fireplace: lein repl and connect to remote repl
• Cider: M-x cider-jack-in to start repl or lein repl and M-x cider-connect
• Run (go) on the repl

File tree

Common

• Source files are separated per filetype, common practice(?)
• Helpful as some files have different roles
  • Cljs files are input only
  • Clj is input only if AOT compiled, but input+output if no AOT
• src/clj
• src/cljc
• src/cljs
• src/less
• test/clj
• test/cljc
• test/cljs

Boot

• build.boot Boot entry file
• boot.properties Java properties file, defines Boot version used
  • by the time build.boot is read, Boot is already running - need for separate file
• src/cljs/js/main.cljs.edn configuration file for Boot-cljs, will result in result being written to js/main.js path inside the fileset.

Lein

• project.clj Lein configuration file
• lein-target The directory used for files written by Lein stuff, in development some parts are included in classpath to serve files from

Cljs macros are defined in Clj files, where would you place such file?

TODO

• boot-clj/boot-cljs#95
• New boot-cljs release for compiler-options precedence change
• Less4clj 1.9.0-alpha12 compat
